We were wondering why we hadn't seen these two together for nearly six weeks now!

Heidi Klum and her bodyguard/boyfriend Martin Kirsten have split after about a year and a half of dating, a source close to the couple confirms to People magazine. The two parted ways a few weeks ago, and the insider added that they are "no longer working together." Ruh roh! He lost his woman and his job?!

"Martin was there for her during a challenging time in her life and it was something she will always be grateful for," the source added. "Life is about timing. He was incredibly supportive and they were there for each other, but they're moving on now. They still have a great friendship."

Wonder who she's gonna date next?
